Nasmille L. Larke-Mejía

I am an MSCA postdoctoral fellow working on the μ-Arctic project, focused on microbial isoprene cycling in the Arctic and based at the Center for Volatile Interactions (VOLT) at the University of Copenhagen, Denmark. I completed my PhD and research placement at the University of East Anglia, United Kingdom, where my work centered on bacterial degradation of isoprene. I also held a postdoctoral fellowship with the UKRI-funded GROW Colombia project, where I studied soil health in sugarcane plantations and investigated the fungal phytopathogen Mycena citricolor. My ongoing research aims to deepen our understanding of microbial processes across different environments and their implications for climate change and ecosystem health.
